explains how to install Sailfish on Nexus 5, for that one needs to make few steps under cyanogen, one of which is
in case you didn’t know it about playstore. okay. aha.

work in oberon v4 system (in this example it’s used over windows).

Note how he’s able to compile source which exist only in window (marked by asterisk), how he calls exported module functions from the environment.

Running 4 copies of an operating system at once
Dick explained to me that they were using an operating system from a company called Telesoft. Telesoft, headed by UCSD Pascal author Ken Bowles, was building an Ada compiler on top of its ROS (Renaissance Operating System) product. He told me (and I remember this clearly) that they had the operating system running in single user mode but that they wanted to run it in multi-user mode. At that point I was barely 21 years old. I had written a whole bunch of system-level 6502 assembler code and I had a really good ground-up understanding of the way that contemporary computer hardware worked. After studying the manual for the SUN board, I decided that I could simply break the 2MB of physical memory in to 4 chunks of 512KB each and run 4 copies of the operating system, gaining control via interrupts and device drivers.

I was thinking, that single space os should have weak security, but it seems I was wrong. This is a very interesting paper -Sharing and Protection in a Single Address Space Operating System
This paper explores memory shanig and protection support in Opal, a single address space operating system designed for wide address archtectures. Opal threads execute within protection domains in a single shared virtual address space. Sharing is simplified, because addresses are context-independent.

The second operating system hiding in every mobile phone
I’ve always known this, and I’m sure most of you do too, but we never really talk about it. Every smartphone or other device with mobile communications capability (e.g. 3G or LTE) actually runs not one, but two operating systems. Aside from the operating system that we as end-users see (Android, iOS, PalmOS), it also runs a small operating system that manages everything related to radio

New edition of Wirth’s book Project Oberon is out. It describes not only built from scratch software(entire operating system and compiler), but design of the hardware as well.
The vast complexity of popular operating systems makes them not only obscure, but also provides opportunities for “back doors”. They allow external agents to introduce spies and devils unnoticed by the user, making the system attackable and corruptible. The only safe remedy is to build a safe system anew from scratch.

So the idea is to tie everything so hard into systemd that alternatives will just be impossible because of undocumented, unportable APIs that are leaky abstractions that make no sense without the thing they fail to abstract?
And why on earth does every daemon now need to be patched? They worked well for the last few decades without such specific hackery.
very good text by Gentoo developer Patrick Lauer about systemd.

The Full Story of #Nokia and #Microsoft - How we got here, and why Microsoft will fail with Nokia handsets just like it did with Kin http://communities-dominate.blogs.com/brands/2013/09/the-full-story-of-nokia-and-microsoft-how-we-got-here-and-why-microsoft-will-fail-with-nokia-handset.html
Ok the news is out. I told you literally two years ago, that the Windows Phone strategy would be the death of Nokia’s handset business, and today we have the final nail in that coffin. I honestly, truly with my hand on my heart, hoped this day would never come, and that my prediction would be seen as wrong. But unfortunately I was correct (once again). I do tend to know this industry. And I was the first to tell you, on this blog, that Nokia’s handset business just died. I told you when it happend, and more importantly, I told you why it died. It didn’t die with the crazy Burning Platforms memo, nor with the announcement of Microsoft Windows Phone either. So this is my (first) full epitaph to Nokia. And we have to have a bit of history. (Long blog warning - this runs 12,000 words, so get yourself a cup of coffee, this will take about half an hour
